Merge tag 'drm-misc-next-2021-10-06' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.16:

UAPI Changes:
- Allow empty drm leases for creating separate GEM namespaces.

Cross-subsystem Changes:
- Slightly rework dma_buf_poll.
- Add dma_resv_for_each_fence_unlocked to iterate, and use it inside
the lockless dma-resv functions.

Core Changes:
- Allow devm_drm_of_get_bridge to build without CONFIG_OF for compile testing.
- Add more DP2 headers.
- fix CONFIG_FB dependency in fb_helper.
- Add DRM_FORMAT_R8 to drm_format_info, and helpers for RGB332 and RGB888.
- Fix crash on a 0 or invalid EDID.

Driver Changes:
- Apply and revert DRM_MODESET_LOCK_ALL_BEGIN.
- Add mode_valid to ti-sn65dsi86 bridge.
- Support multiple syncobjs in v3d.
- Add R8, RGB332 and RGB888 pixel formats to GUD.
- Use devm_add_action_or_reset in dw-hdmi-cec.

-Use DRM_MODESET_LOCK_ALL_* helpers instead of boilerplate
----------------------------------------------------------
-
-For cases where drivers are attempting to grab the modeset locks with a local
-acquire context. Replace the boilerplate code surrounding
-drm_modeset_lock_all_ctx() with DRM_MODESET_LOCK_ALL_BEGIN() and
-DRM_MODESET_LOCK_ALL_END() instead.
-
-This should also be done for all places where drm_modeset_lock_all() is still
-used.
-
-As a reference, take a look at the conversions already completed in drm core.

 Compared to normal mutexes two additional concepts/objects show up in the lock
 interface for w/w mutexes:
 
-Acquire context: To ensure eventual forward progress it is important the a task
+Acquire context: To ensure eventual forward progress it is important that a task
 trying to acquire locks doesn't grab a new reservation id, but keeps the one it
 acquired when starting the lock acquisition. This ticket is stored in the
 acquire context. Furthermore the acquire context keeps track of debugging state

  *
- * &drm_bridge, like &drm_panel, aren't &drm_mode_object entities like planes,
- * CRTCs, encoders or connectors and hence are not visible to userspace. They
- * just provide additional hooks to get the desired output at the end of the
- * encoder chain.
+ * The interaction between the bridges and other frameworks involved in
+ * the probing of the upstream driver and the bridge driver can be
+ * challenging. Indeed, there's multiple cases that needs to be
+ * considered:
+ *
+ * - The upstream driver doesn't use the component framework and isn't a
+ *   MIPI-DSI host. In this case, the bridge driver will probe at some
+ *   point and the upstream driver should try to probe again by returning
+ *   EPROBE_DEFER as long as the bridge driver hasn't probed.
+ *
+ * - The upstream driver doesn't use the component framework, but is a
+ *   MIPI-DSI host. The bridge device uses the MIPI-DCS commands to be
+ *   controlled. In this case, the bridge device is a child of the
+ *   display device and when it will probe it's assured that the display
+ *   device (and MIPI-DSI host) is present. The upstream driver will be
+ *   assured that the bridge driver is connected between the
+ *   &mipi_dsi_host_ops.attach and &mipi_dsi_host_ops.detach operations.
+ *   Therefore, it must run mipi_dsi_host_register() in its probe
+ *   function, and then run drm_bridge_attach() in its
+ *   &mipi_dsi_host_ops.attach hook.
+ *
+ * - The upstream driver uses the component framework and is a MIPI-DSI
+ *   host. The bridge device uses the MIPI-DCS commands to be
+ *   controlled. This is the same situation than above, and can run
+ *   mipi_dsi_host_register() in either its probe or bind hooks.
+ *
+ * - The upstream driver uses the component framework and is a MIPI-DSI
+ *   host. The bridge device uses a separate bus (such as I2C) to be
+ *   controlled. In this case, there's no correlation between the probe
+ *   of the bridge and upstream drivers, so care must be taken to avoid
+ *   an endless EPROBE_DEFER loop, with each driver waiting for the
+ *   other to probe.
+ *
+ * The ideal pattern to cover the last item (and all the others in the
+ * MIPI-DSI host driver case) is to split the operations like this:
+ *
+ * - The MIPI-DSI host driver must run mipi_dsi_host_register() in its
+ *   probe hook. It will make sure that the MIPI-DSI host sticks around,
+ *   and that the driver's bind can be called.
+ *
+ * - In its probe hook, the bridge driver must try to find its MIPI-DSI
+ *   host, register as a MIPI-DSI device and attach the MIPI-DSI device
+ *   to its host. The bridge driver is now functional.
+ *
+ * - In its &struct mipi_dsi_host_ops.attach hook, the MIPI-DSI host can
+ *   now add its component. Its bind hook will now be called and since
+ *   the bridge driver is attached and registered, we can now look for
+ *   and attach it.
+ *
+ * At this point, we're now certain that both the upstream driver and
+ * the bridge driver are functional and we can't have a deadlock-like
+ * situation when probing.
